Full Bio
Hello my lovely darlings! I'm Em, a novice freelance model based out of Vancouver in the beautiful province of British Columbia, Canada. I absolutely love Pin-Up style: the over-the-top expressions, the dresses, the vintage lingerie, the make-up, the curls. I adore it all! I am especially over the moon about anything 40s and 50s inspired - think tea length swing dresses, circle skirts, and polkadots! I also enjoy me a good wiggle dress, of course!
I would love to get to shoot more pin-up looks! If you're interested in working together, please let me know a little bit about yourself 🙂
